COLD-WATER SQUIRT.

Specification of Letters Patent.

Patented Mar. 27, 19 17.

Application filed July 17, 1914. Serial No. 851,455.

To all whom it may concern:

Be it known that I, ALFRED GILLIS, of Baltimore, in theSt-ate ofMaryland, have invented a certain new and useful Improvement inCold-Water Squirts, and do hereby declare that the following is a full,clear, and eXact description thereof.

My invention relates particularly to devices for providing a stream ofcold water for sprinkling the coal, etc, used in connection with alocomotive, although it is equally applicable to other similar purposes.

Hitherto in order to provide a stream of water for this purpose, it hasbeen customary to attach a hose to the boiler. An apparatus of this kindhas been found very undesirable, and in fact, even dangerous owing tothe blowing off of the hose and the scalding and burning of the firemen.The use of hot water for this purpose is generally disadvantageous asthe hot water issuing from the hose may scald the firemen.

The object of my invention is to provide an apparatus for use onlocomotives and in any similar locations, in which a stream of coldwater may be readily provided in a simple manner and withoutany dangerof scalding the firemen or other persons using the stream of water.

While my invention is capable of embodiment in many difierent forms forthe purpose of illustration I have shown only one form thereof in theaccompanying drawings, in which,

Figure 1 is a horizontal section of an apparatus made in accordance withmy invention; Fig. 2 is a central longitudinal section through the checkvalve shown in Fig. 1; and Fig. 3 is a longitudinal section through thequick-opening valve shown in Fig. 1.

In the drawings, I have shown a supply pipe 1 for steam which isscrew-threaded to a pipe joint 2 having on one side thereof a branchinlet 3 for cold water to which is at tached a check valve casing 4communicating with a. water inlet pipe 4. The check valve casing 4 hasin its interior a check valve 5, which is loosely supported upon aswinging arm 6, by means of a nut 5 the swinging arm being supported inpivots 7 within the casing 4. Upon the top of the casing 4 there is aremovable plug 8 to give access to the check valve and upon the sides ofthe casing 4 there are removable plugs 9 to give access to the pivots 7while a further plug 10 upon the top of the casing 4 is provided topermit access to the nut 5 which is attached to the check valve 5., Theinlet 3 opens into an annular chamber 11 in the-interior of the pipejoint 2, said chamber 11 surrounding a nozzle 12, which communicateswith the passageway in the steam inlet pipe 1. Connected to the outletend of the pipe joint 2 there is a connecting pipe 13 which leads fromthe pipe joint 2 to a quick opening valve casing 14. The connecting pipe13 has in its interior a reduced passageway 13 connected with a taperedpassage way 13 at the inlet end of the connecting pipe 13 and which isconnected with a tapered outlet passageway 13 at the outlet end of theconnecting pipe 13. In the valve casing 14 there is a transversepassageway 15, in which there is adapted to swing an arm 16 carried upona shaft 17 to the end of which shaft there is attached a handle 18. Thehandle is retained in placeby a nut 19 and a stuffing box 20 preventsthe escape of fluids around the shaft 17. At the end of the lever 16within the transverse passageway 15 there is a ring 21' which supportsupon either face thereof a valve member 22 having a fiat surface 23 anda centrally located raised portion 24, which raised portion rests withinthe center of the ring 21. On the valve casing 14, immediately oppositethe transverse passageway 15, there is a re-- movable plug 24 to giveaccess to the interior of the casing 14. Any suitable type of hose 25,designed for conveying cold water may be applied to the outlet end ofthe valve casing 14.

In the operation of the apparatus, assuming that the valves are inclosed position, steam will be present in the inlet pipe 1 and in thepassageway in the connecting pipe 13. When it is desired to provide astream of cold water for the purpose of spraying the coal on alocomotive tender or for any other desired purpose, the handle 18 ismoved so as to quickly and immediately open the swinging valve to whichit is connected, that is -to say, by moving the valve members 22 in thetransverse passageway 15 so as to open communication between the inletand outlet ends of the valve casing 14. The steam within the apparatusthen immediately escapes through a hose 25 drawing with it at once thecold water through the check valve and through the branch inlet 3.Because of the quick opening of the valve, cold water is thereforeimmediately supplied through the hose 25, and thereafter cold waterpasses out continually from the end of the hose 25, thus avoiding anypossibility of scalding the firemen by steam or hot water. WVhen the supply of cold water is no longer needed, the handle 18 is again operatedto close the valve and the pressure of the steam then prevents theescape of water by closing the check valve within the casing at. If anyadjustment or repair is necessary to the valves, the same can be readilymade by removing the proper plug to give access to the particular valve.

While I have described my invention above in detail, I wish it to beunderstood that many changes may be made therein without departing fromthe spirit of my invention;

I claim:

1. A cold water delivery device comprising an injector, a steam pressuresupply pipe connected therewith, a water supply pipe therefor, and adelivery valve device at the outlet from the injector adapted to performthe combined action of controlling the flow of steam and water into andthe delivery of water from said injector.

2. A cold water delivery device comprising an injector, a steam pressuresupply pipe giving at all times a free access of steam to said injectorand connected therewith, a water supply pipe therefor, and a quickactingvalve device at the outlet from the inector adapted to perform thecombined action of controlling the flow of steam and water into and thedelivery of water from said injector.

3. A cold water delivery device comprising an injector, a steam pressuresupply pipe giving at all times a free access of Copies of this patentmay be obtained for five cents each, by addressing the steam to saidinjector and connected there with, a water supply pipe for saidinjector, a check valve in said water supply pipe opening toward saidinjector, and a delivery valve at the outlet from the injector whichperforms the combined action of controlling the flow of steam and waterinto and the delivery of water from said injector.

4:. A cold water delivery device compris ing an injector, a steampressure supply pipe giving at all times a free access of steam to saidinjector and connected therewith, a water supply pipe for said injector,a check valve in said water supply pipe opening toward said injector,and a swinging delivery valve at the outlet from the injector whichperforms the combined action of controlling the flow of steam and waterinto and the delivery of water from said injector, which rotates in aplane located at right angles to the outlet pipe in which the valve issituated. I

5. A cold water delivery device comprising an injector, a steam pressuresupply pipe giving at all times a free access of steam to said injectorand connected therewith, a water supply pipe for said injector, aswinging check valve in said water supply pipe opening toward saidinjector, and a delivery valve at the outlet from the injector whichperforms the combined action of controlling the fiow of steam and waterinto and the delivery of water from said injector.

In testimony that I claim the foregoing I have hereunto set my hand.
